SOURCE: I need to replace timing chain on 89 cadillac seville

Need to look at the distributor first and make sure its tightened down and cannot be easily rotated. May have gotten out of time enough to mess up the gear on the bottom of the distributor too...

You didn't include the mileage so I'm assuming its fairly high..

Could be the cap too they short internally and mess up good

Blown timimng belt,how do i retime engine when replacing timing belt

Ok first thing is remove the #1 spark plug from engine, then turn your crank until you feel air push out that cylinder that means you are at TDC (top dead center). You will then set your cams to there settings ( I am not sure if this is a inline 4 or v6) so I can't tell you the marks. But the cams pulley will have marks that will align to marks on the head, The crank will have a mark on the pulley and on the block line these up as well. I like to set the top cam marks first then clamp the belt and pulley together with a small clamp to keep the tension. after that is all lined up install the tensioner and make sure you adjust the tensioner it will have two small pin holes that will need to be turned in order to tighten the tension. ( not to loose or belt can skip, not to tight or belt will wine.) Also if the belt snap while driving you probably bent the valves and will have to do a valve job which requires removing the head,

Need to know what the degree the timing should be for a4.9 Cadillac Engine ?

The 1991 Cadillac DeVille 4.9 engine incorporates a magnetic timing probe hole for use with special electronictiming equipment. Malfunction codes may be set during ignition timing adjustment procedure.Enter diagnostics and clear trouble codes if this occurs.#1 Place transmission in park .#2 With the ignition in the Off position attach a timing light to #1 spark plug cable .#3 With engine at normal operating temperature and air conditioning OFF,take off the air cleaner upper housing. The engine should be OFF at this point.#4 Jump pins A and B at the ( ALDL) connector.while not in diagnostic display.SET TIMING MODE message will apear on the climate control Driver Information center.#5 Start the engine and aim the timing light the timing mark loosen the distributor hold-down nut. While observing the timing mark, rotate distributor untill the line indicates the correct timing .This sets the base timing at 10 degrees BTDC at any speed under 800 RPM in the (PCM) The PCM controles the timing throughout the intire engine RPM range.This is the best imformation I can offer you good luck.
